Used it on the bare metal (aluminum) on the bottom edge of the windscreen as well as the scuffed up roll bar. Makes for a nice bead on the inside. After that I layed up the fiberglass transition with Hysol instead of West System epoxy per tech counselor advice. Hysol sticks great to aluminum and plexi. Made some test samples and literally had to destroy them and they still did not come apart.
